BACKGROUND The host response to tissue injury requires a complex interplay of diverse cellular, humoral, and connective tissue elements. Fibroblasts participate in this process by proliferating within injured sites and contributing to scar formation and the longterm remodeling of damaged tissue. Fibroblasts present in areas of tissue injury generally have(More)
Proteins associated with autosomal dominant and autosomal recessive polycystic kidney disease (polycystin-1, polycystin-2, and fibrocystin) localize to various subcellular compartments, but their functional site is thought to be on primary cilia. PC1+ vesicles surround cilia in Pkhd1(del2/del2) mice, which led us to analyze these structures in detail. We(More)
Urinary exosome-like vesicles (ELVs) are a heterogenous mixture (diameter 40-200 nm) containing vesicles shed from all segments of the nephron including glomerular podocytes. Contamination with Tamm-Horsfall protein (THP) oligomers has hampered their isolation and proteomic analysis. Here we improved ELV isolation protocols employing density centrifugation(More)
The Nephrotic Syndrome Study Network (NEPTUNE) is a North American multicenter collaborative consortium established to develop a translational research infrastructure for nephrotic syndrome. This includes a longitudinal observational cohort study, a pilot and ancillary study program, a training program, and a patient contact registry. NEPTUNE will enroll(More)
Renal involvement is a frequent consequence of plasma cell dyscrasias. The most common entities are light chain amyloidosis, monoclonal immunoglobulin deposition disease and myeloma cast nephropathy. Despite a common origin, each condition has its own unique histologic and pathophysiologic characteristic which requires a renal biopsy to distinguish. Recent(More)
Urinary extracellular vesicles (uEVs) are released by cells throughout the nephron and contain biomolecules from their cells of origin. Although uEV-associated proteins and RNA have been studied in detail, little information exists regarding uEV glycosylation characteristics. Surface glycosylation profiling by flow cytometry and lectin microarray was(More)
OBJECTIVE Prospective evaluation of pregnancy outcomes in pregestational diabetes along the Atlantic seaboard 2006-2007. RESEARCH DESIGN AND METHODS The Atlantic Diabetes in Pregnancy group, representing five antenatal centers in a wide geographical location, was established in 2005. All women with diabetes for >6 months before the index pregnancy were(More)
Acute infection with Epstein-Barr virus (EBV) causes fever, fatigue and pharyngitis. Renal involvement in systemic EBV infections typically manifests as acute tubular necrosis or tubulointerstitial nephritis. Rarely, EBV infection causes nephrotic syndrome due to minimal change disease. A 22-year-old male with infectious mononucleosis (IM) presented with(More)
